The first thing i would look at is the fuel pump, make sure your getting fuel preasure, another thing is to scan the computer for any stored codes, these codes will tell you what part of the system is failing, these had alot of problems with the ignition switch, but would not make the car die out, it would just get it from starting,if this is a problem then there will be a code for the anti theft ignition system. start with fuel preasure.

Hi. No enough details to point the finger. Check your battery and charging system first and let me know. What kind of "hiccups " you were having?

98' jeep starts sometimes


The next time it fails to start, you'll need to start crossing off the possible causes. Is it lack of fuel or lack of spark ? Is the asd relay working, and so on. Once you narrow down the causes you can troubleshoot it better.

Engine failure


When a catalytic converter is coming apart on the inside, it can restrict air flow and power, and it usually happens or gets worse when the vehicle has been running long enough to generate a lot of heat. Once it cools down, the symptoms can completely go away until you begin to drive it again. It's one possibility.

Check the battery connections and cables. A loose cable or corrosion on a connector can give intermittent shorting that will prevent the car from starting/running. Your problem may be solved by simply tightening/replacing a cable or cleaning the battery posts.

On the 1999 - 2000 5.7 vortec engines the distributor gears wear causing the timing to change 2 or more degrees. The ecm is designed to shut down at 2 or more degreedifference. This is in a GM bulletin that recommends replacement at 160k miles. Mine went out at 150k miles. Very similar driving symtoms until it quit running. Both cam sensor codes were set on mine though, not the crank sensor.
